The cutaneous manifestations of tuberculosis can be grouped into two categories: (1) those in which actively multiplying tubercle bacilli are present in the lesions, and (2) those, the tuberculids, in which tubercle bacilli or their products embolize to the skin from some active, but at times obscure focus of the disease. In tuberculids, the embolized bacilli do not long remain viable, apparently because of the intense tissue reaction elicited by their presence in the skin.1,2 Two well-defined types of tuberculids are papulonecrotic tuberculid and erythema induratum. In this report we present evidence that the extreme tuberculin sensitivity which characterizes these tuberculids3 can best be demonstrated with old tuberculin (O.T.) rather than with more purified derivatives such as the purified protein derivative (PPD).
It is of interest that Darier4 in 1896 introduced the concept of tuberculid before knowledge about tuberculin skin testing was developed shortly after the turn
